This is the highest-end model of the ELSZ series, which enables measurement of zeta potential and particle size in dilute to concentrated solutions as well as molecular weight measurement. As a new function, we have adopted multi-angle measurement to improve the resolution of the particle size distribution. It also enables particle concentration measurement, microrheology measurement, and gel network structure analysis.
The new zeta potential plate cell unit has a newly developed coating for high salinity, which enables measurement in a hypersaline environment such as physiological salt solution. We also have a lineup of ultra-trace cell units that measures particle size only with micro-volume samples of 3μL, expanding the possibilities in the life science field.
It measures particle size and zeta potential in a wide concentration range from dilute to a concentrated solution (~ 40%)
Multi-angle measurement enables measurement of particle size distribution with high resolution
Zeta potential of the flat sample can be measured under a hypersaline environment
Particle concentration can be measured using the static light scattering method
Microrheology measurement is possible by the dynamic light scattering method
It is possible to evaluate the network structure and non-uniformity of the gel by measuring multiple points of the gel sample
Continuous measurement of particle size and zeta potential is possible with a standard flow cell
It has a wide temperature range between 0 and 90℃
Degeneration, phase transition temperature analysis of proteins, etc. are possible by the temperature gradient function
It provides highly precise zeta potential measurement results by measuring the electro-osmosis flow and plot analysis in the cell
*Fluorescent cut filter can be attached
